Figure 2From: Pseudodiaptomus marinus Sato, 1913, a new invasive copepod in Lake Faro (Sicily): observations on the swimming behaviour and the sex-dependent responses to food Probability density functions and mean speed values (dashed lines) of the mean swimming speed. (a) Males, (b) females and (c) ovigerous females of P. marinus in conditions without food (red line) and in presence of food in excess (green line). Mean speed values for males and ovigerous females in feeding and non-feeding conditions are overlapping.Back to article page
